Backflow Test Results

With our experience of testing thousand of backflows we have gathered stats on the most commonly used backflows to which ones are most likely to need repairs. Backflows fail for a number of reasons. The main reason for failure is because of mechanical failure.

The largest mechanical failure is because the Poppet valve fails. 

  • The Poppet valve is a one way valve mechanism that prevents contaminated water from entering your local drinking water supply.
  • It is in most cases, these poppet valves are made of plastic and open and shut thousands of times in their lifespan.
  • Thus the need to annually inspect and test backflow valves.
